ich verstehe nicht, inwiefern hashkeys wartbarer sein sollen. Z.B. Packagevariablen sind doch letztlich auch nur Einträge in %main:: respektive %packagename::

When you write my $x = 1, the effect is confined to the current block. When you write $main::x = 1, you can figure out the effect by looking through the program to see who looks at $main::x. The instant you write $$name = 1, you don't know any more what the effect will be or where it will crop up; it could be anywhere. You have just turned every 25-line debugging problem into a potential 700-line debugging problem.

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. -- Damian Conway in "Perl Best Practices"
